How to construct an API that would contain a white space within the name of a brain structure - SOLVED

I would like to build an API equivalent to this one, offered as an example in the API section of the Allen Brain web:[injection_structures$eqIsocortex][primary_structure_only$eqtrue]

but changing “Isocortex” for other ontology terms that contain white spaces, for example “Olfactory areas”.

I have tried either with the white space, or changing it for “-”, “_” or "\ ", without success.

SOLVED: You need to use the abbreviation, “OLF” in this case, instead of the full name.
